Programming Dandelion for Nikon
Programming of Dandelion includes three simple steps:
Activate Dandelion program mode by making 3 successive shots with the following shutter speed:
If your camera does not have a 5 sec shutter speed, use 6 sec. Your screen will show aperture changing by itself in rounds:
This means that Dandelion has entered program mode. Commands are input with a 1 sec. shot when a certain aperture value appears on the screen. You cannot choose an aperture value with a controller on your camera. You will have to wait until the needed aperture value appears on the screen. If you miss the value you need, you will have to choose it when it appears again during the next round. If you don't make a shot after three rounds, Dandelion will exit program mode automatically.
To force exit simply turn your camera off.
Make one shot at aperture 2.8. Aperture will start changing in rounds, but this time from F1 to F90.
Choose the value you need. You can only choose aperture values the camera displays.
Make a shot at the value you need. Dandelion will memroize it and exit program mode.
Make a shot at aperture value 4.5.
The aperture will continue changing, this time from F1 to F90.
Here each value corresponds to focal length according to the table:
Make a shot when the needed aperture value appears.
Dandelion will memorize its corresponding focal length and exit program mode.
Works similar to lens switch. Simply make a shot when aperture value 5.6 appears
and the focus mode will switch. Dandelion will then exit program mode.
You can move autofocus confirmation dot slightly forward or backward by experimentally moving justification constant. One shot at aperture value 10 moves the dot back. Aperture 20 moves the dot forward. The range consists of 17 positions. On default 9 (middle position) is used. Move the confirmation dot forward or backward and try to adjust sharpness. The best justification distance is 3-5 meters. To exit justification mode turn your camera off.
If Dandelion is installed on a lens with an automatic instant-return aperture of AI-S type, you will have to unblock the aperture control function by setting Dandelion to your lens's minimal aperture value which usually equals to 16 or 22. For correct functioning of an instant-return aperture you will first have to set Dandelion to the fully-open aperture value. You can do this with the help of function 2.8. Then use the following function of minimal aperture value change. Make one shot at aperture value 40. Aperture will start changing its values round by round, from F1 to F90. Choose the value you need. Normally it will be 16 or 22. Make one shot when the aperture value you need appears. Dandelion will memorize it and exit program mode. After that you will be able to work with your aperture in the same way as with an AF lens. Close the aperture on your lens, thus setting it to its minimum. Let it stay that way forever. Then you can choose aperture value, adjust sharpness, make shots, etc, with your main dial. Note: In pre-AIS series lenses manufactured before 1981 the aperture control mechanism has a non-linear construction. When making pictures with such lens a slight expo correction may be needed. AI-S lenses with linear aperture of the new type can be distinguished by a special marking: minimal aperture value is marked in red on the main and additional scales. Additional information and photos can be found here. New AI-S series includes Samyang and Zeiss ZF lenses.
Make a shot when aperture value 90 appears.
Dandelion will reset its default settings (45/2.8, AF, justification 9) and exit program mode.
